Hello "Lady"!
Samourai Sauce is a Belgian concoction, I believe. It is a fairly spicy mayo served with Pommes Frites. I thought it might taste better with a home-made recipe!
Thanks for the response!

Welcome mahnparis! Perhaps if you checked out the forum on Dutch Mayonnaise you might find what you are looking for. There were plenty of variations brought out there._________________Vivant Linguae Mortuae!!

mahnparis: I'm wondering if you added HP's Curry Sauce to mayo, if that would do what you want. My partner is Scottish and they serve Curried Chips everywhere in the U.K. We've found HP products in many stores in Chicago, so we slather our home fries in the sauce and it's just like London, at 4:00 am, after a good pub crawl.

Here's some interesting bits on Belgian Fries and sauces. All youz New Yawkers (Erin!) can go and have some fun!

"Pommes Frites isn't an ordinary shop, but a specialty shop serving authentic Belgian fries, or as the Belgians call them, "pommes frites." You won't find many seats here, but you will find the tastiest treat in town. Pommes Frites means premium fresh fried potatoes, crunchy on the outside, and soft inside: self-indulgent and pleasurable. The atmosphere is intimate and warm, the packaging and signage unique. Pommes Frites isn't only selling affordable food, but excitement and an experience, too. There is no fancy skill involved, but there is a trick. The potatoes are fried twice. The first time they are cooked through. The second time provides a golden color and makes them deliciously crisp. Europeans have been eating their fries with everything but ketchup for many years, and now Americans may also have the best crispy fried potatoes with their choice of sauce. Americans (those who have experienced Pommes Frites) seem to be extremely pleased that fries can be prepared differently and served with a variety of goodies, other than ketchup. For example, you can eat them with exotic mustards and mayonnaise, or drowned in vinegar, curry sauce, or even with a peanut satay sauce. All are for sale at Pommes Frites. The selection of toppings for your frites includes everything from the familiar to the exotic, and is limited only by imagination. Pommes Frites sales' policies include allowing the customer to sample the frites and taste any and every sauce until satisfied. With the help of the amazing potato, Pommes Frites will continue to join the ranks of other famous street foods and become a part of American culture."

Here's the sauces they serve on their Pomme Frites; WOW! talk about extensive selection!

Poutine is a French-Canadian dish made from a combination of French fries, chicken gravy, and curd cheddar cheese.
The cheese and the gravy are imported especially from Quebec to give our customers the most authentic and enjoyable experience."

Apparently this is a very popular place in New York. Here's one of 43 reviews of this little shop: "Belgian-style fries served to-go in a cone.

In Short
On a good day, this tiny East Village storefront goes through more than 1,000 pounds of potatoes. Folks line up for a cone filled with fries and loaded up with one or two of the 26 cheesy, meaty toppings. Authentically Belgian, the fries here are hand-cut and twice-fried, but the dippings span the globe: roasted garlic mayonnaise, satay peanut sauce and the complimentary house-special mayonnaise, ketchup and raw onions."
